9 Claims.

This invention relates to a structurally and functionally improved roughing head and/or element, which may be capable of use invarious associations, but is primarily intended to be em- 5 ployed in the manufacture of shoes and similar articles, and especially by means of which the outsoles of shoes may be roughened.

It is an object of the invention to provide an article of this character by means of which uniform and rapid results may be obtained.

A further object of the invention is that of constructing roughing elements which will have a far longer effective life than similar elements as heretofore provided.

A still further object is that of constructing a roughing element which, if desired, may be reconditioned to have a further useful life after its surfaces have once become dulled.

Another object is that of providing a head which will adequately support various types of roughing elements, but which is primarily intended to be utilized in. connection with elements embodying a construction as taught by the present invention. Regardless, however, of the type of element which is employed, a head constructed in accordance with the present invention will serve to rigidify and strengthen the individual elements aside from the fact that the depth of roughing may be accurately gauged by the use of this head.

An additional object is that 'of furnishing a roughing element which in itself will embody a structure extremely resistant to accidental breakage or distortion.

Among still further objects of the invention are those of providing a roughing head and/or element which will individually and collectively include extremely simple structures, embracing relatively few and rugged parts, these parts being capable of use by comparatively unskilled labor, and capable of being produced at relatively low cost. Additionally, these parts may be quickly assembled, and, when so assembled, will provide a unitary and mutually cooperative structure capable of use over long periods of time with freedom from difl'iculties. Moreover, when it does become necessary torenew or replace any of theelements of the assembly, this 'may be done with'the expenditure of only minimum eifortand time.

With these and other objectsin mind, reference is had to the attached sheet of drawing illustrating practical embodiments of the invention, and in which '55 Fig. 1 is a partly sectional front view of a roughing machine and showing a head and elements constructed in accordance withthe teachings of the present invention associated therewith;

Fig. 2 is a side elevation of such head and elements;

Fig. 3 is a bottom plan view of the unit as illustrated in Fig. 2;

Fig. 4 is a sectional side view taken along the lines 4-4 as indicated by the arrows in Fig. 3;

Fig. 5 is a side elevation of one of the roughing elements; and I Fig. 6 is an enlarged end view thereof.

Referring primarily to Fig. 1, it will be noted that in this view there has been illustrated one form of roughing machine. This is, of course, merely for the purpose of showing the invention in such association. It is obvious that any other form of machine may utilize the teachings of. the present invention.

Thus, in Fig. 1 the numeral [0 indicatesa table,

which may be supported as at H, and which is formed with anopening through which soleengaging and work-supporting rollers-respectively indicated at [2 and l3-may. extend. Above the table a feeding roller I4 may be provided, and these rollers engage between them a sole IE, to be roughened. Extending preferably above the table is a support l6, for a rotary spindle l1, and this spindle supports and drives the head, generally indicated at I8. Adjacent the head a sole-guide [9 may be mounted. It will, of course, be appreciated that suitable mechanism (not shown) is provided for operating the feeding roll l4, rotating the spindle l1, and otherwise driving the operating parts of the machine.

Now referring to Figs. 2 to 4, it will be noted that a roughing head constructed in accordance with the teachings of the'present invention may include a cylindrical. body 20, formed with two annular and concentric series of bores. The individual bores of oneseries are preferably disposed in staggered relationship with respect to adjacent bores of the other series, these bores receiving roughing elements or needles, to be hereinafter describedf The length of the body 20 is, of course, less than the length of the needles or elements, but should, in any-event, be adequate to firmly support the needle bodies. Moreover, while the body of the head may be secured to the spindle I! in any desired manner, it is preferable that this be accomplished by forming such body with a central bore or well, which may be screw threaded, as at 22, to repart carried by the spindle. The bore 2| may be continued and, if desired, reduced, to extend through to the lower face of the body 20. This extension may also be screw threaded to receive the threaded stem 23 of a gauge plate 24. In this manner it is obvious that the distance between the plate and the outer face of thebody may be adjusted and, when such adjustment has once been achieved, the parts may be locked against further movement by a nut encircling the stud.

As has been especially shown in Fig. 3, the gauge plate 24 is formed with an annular series of openings to align with the innermost series of bores formed in the body 28, and this plate is, in the present exemplification, formed with aseries'of notches in its edge,'which notches-align with the outermost series of bores formed in such body. While the latter construction is, of oourse,.notv essential, it is, according to. many aspects, preferable, for the reason that it is. .de-. sirable to have the roughingelements or needles of the outermost series a major distance to one side of the spindle axis, and by having these notches it is, of course, unnecessary. to have the gaugerplate extend beyond the face of the body 20.

As afore brought out, a head. of this construction maybe utilized in connection with various types of roughing needles or elements. However, it is preferred that it be employed in connection with elements or needles of a construction such as taught in the present specification,- it being also preferred that such novel needles or elements be utilized with a head of this type. As shown, especially in Figs. 4 and 5, these needles include bodies 26, which may pass through the bores formed. in the head 20, and which are of such length that they will extend beyond the upper face of. this body and below the lower face of the gauge. plate. At their upper ends these elements, are formed with. heads. 21-, which prevent the needles. from falling. through, the bores, and at their lower ends the. needles-terminate in points which are developments of surfaces 28 extending inwardly and angularly with respect to each other. These. surfaces may, of course, be formed by grinding and, as shown, may be three in number. However, regardless of their number, it. will be seen that along the lines of juncture of adjacent surfaces, edgeportions are formed which, in conjunction with the points, will effectively cooperate with the. surface of the sole or other work. Also, due .to the provision of these surfaces, a rigidifying factor is embodied in the needles which will tend materially to. strengthen the same and reduce the liability of breakage.v

In use it. will be appreciated thatii. the head and elements. are constructed as illustrated, an operator will primarily adjust the gauge-plate to lie in a plane such that the. ends of the needles or roughing. elements. willproject beyond: such plate to justthe. desired extent. Thereafter, he will secure the plate against movement and associate with thehead thusprovided a suitable number of needles inthe manner best shown in Fig. 4. The extended portion or part carried by the spindle I! will now bev introducedin the bore 2|, and the partswill be relatively turned. until they assume. positions locked with respectlto each other. Inthis connection it will be noted. that the spindle I] may carry a flangedmember 29., which will bear against the headsv of the needles 2,102,992 ceive a similarly threaded stud or projecting to prevent any axial shifting thereof. The machine is now ready for operation, and if work is fed through the same and the spindle rotated, the surface of the work will be effectively roughened. Incident to the provision of the head 21, absolute alignment between the several needle points will be assured. As shown in the drawing, the length of the several needles used on a given head,.,fromftheir heads 21 to their points, is substantially identical. Since the heads 21 seat against the flat upper surface of the needle head 20, it follows that the points of the needles will occupy substantially the same horizontal plane. This provides an especially easy and effective way of securing proper relationship of the needle points, and this relationship may read ily be maintained even during subsequent resharpening of the needles since the nature of their points makes it relatively easy to resharpen each needle to exactly the same length as every other needle used on a given head. Also in view 'oftheangular. surfaces2B'it will befound that the work may be performed with greater facility and that the quality of. the work will be more satisfactory, aside from the fact that the roughing elements will remain in proper useful condition for a longer period of time, and, when once dulled, may, if desired, be reground. Due to the provision of the. gauge, the depth of the roughing may be accurately regulated, and, consequently, gouging and pullingof. the sole materialis prevented, This is. aside from the fact that the gaugeacts as a guard which prevents chattering or play on the part ,of, the needles with respect to each other or with, respect to. the head.

Thus,among others, the several. objects of the invention asspecifically afore noted, are achieved. It will be understoodthat numerous changes in construction and rearrangements of the parts might be resorted to... Without departing from the spirit of the invention as. definedby the claims.
